Title: Machine for comminuting bakery products, such as bread remnants and the like
Inventor: CLAHSEN HUBERT
IPC: B02C13/00
Filed: 1982-09-01
Abstract: The machine described has a feed hopper, a pre-comminuter, and a downstream fine grinding device. The pre-comminuter and the fine grinding device are connected together via an annular gap at the periphery of a runner disc carrying a pre-comminuting blade. The axis of the runner is inclined relative to the vertically extending axis of the feed hopper (1), a vertical baffle bar (26) being arranged on the inner wall of the pre-comminuting chamber (23) and reaching to approximately the deepest point of the chamber (Fig. 1). A wedge-shaped pre-comminuting chamber is formed by the oblique position of the runner axis, and the material to be comminuted strikes against the baffle bar in the lower portion of said chamber. The pre-comminuting blades there carry away relatively small pieces of the material which reach the annular gap and fling relatively large pieces upwards into the feed hopper again. A powerful pre-comminution can thus be achieved with low drive power, so that the loading of the downstream fine grinding device becomes smaller. <IMAGE>

Filed: 1983-04-28
Abstract: A device for determining the size and/or distribution of particles contained in a fluid consists of a laser having radial screening of the beam, a lens in the focus of which the measurement volume is arranged and which aligns in parallel light backscattered from the measurement volume, a plurality of annular diaphragms arranged behind one another, concentrically surrounding the screening and having a plurality of concentric annular gaps, and of detectors which are assigned to the annular gaps of the last annular diaphragm and detect the radiation intensity, and an evaluation device. The laser light passes the screen and enters the measurement volume through the lens. The light backscattered by the particle in the focal point passes the lens and is aligned in parallel. Only light of a defined scattering angle corresponding to one of the annular gaps advances up to the last annular diaphragm. In the evaluation device, the intensity ratio is formed for the case of two or more pairs of scattering angles, the values of the ratio are compared to the calculated radiation in the intensity ratio for the three pairs of scattering angles as a function of particle size, and the coincidence value of the particle size, which corresponds to the particle size being sought, is determined for all three pairs of scattering angles.

Title: Engine heat loss recovery unit
Inventor: HAGEN HERMANN DIPL ING DR TECH
IPC: F02G5/02
Filed: 1984-02-02
Abstract: In the exhaust gases of engines with and without exhaust turbocharging the outlet energy of the hot exhaust gases is generally very large. Even in the exhaust turbines of exhaust turbochargers this energy is generally insufficiently utilised. According to the invention the exhaust gas of an engine is expanded in an exhaust turbine to a pressure below atmospheric pressure. In order to bring the gas back up to atmospheric pressure while expending little energy, it is first cooled in an exhaust gas cooler (heat exchanger) to a temperature somewhat in excess of atmospheric temperature and recompressed to atmospheric pressure in an exhaust gas compressor. Since the energy released in the exhaust turbine is greater than that absorbed by the exhaust gas compressor, useful energy remains for the waste heat recovery unit, which energy can be utilised in various ways. The combination of exhaust turbocharging with waste heat recovery, for which purpose the charge air cooling can also be used, is more advantageous for the engine power output, the thermal efficiency and the specific fuel consumption of the engine. The charge air cooling fan is driven here by the unit. By means of the waste heat recovery unit the engine counter pressure can be kept lower than in the case of exhaust turbocharging, which is advantageous for the specific engine fuel consumption. It is also to be noted that the exhaust gas compression may be performed in two or more stages with intercooling, ... Original abstract incomplete. <IMAGE>
